Gymnocalycium: profile
Quick answer
Gymnocalycium baldianum (Chin cactus) is a globular South American cactus with distinctive deep green skin and starburst spine arrangement, producing large showy flowers in white through vivid pink, scarlet, and purple. It thrives in bright indirect light but tolerates lower light conditions better than most cacti; water regularly year-round as the skin loses firmness and becomes squishy if drought-stressed. Native to South America, it grows actively in warm months and slows in winter but maintains water needs year-round. The species name commemorates Italian botanist Virginio Baldian.
Start here:
- 1. Water when top 1-2 inches of soil are dry; maintain consistent moisture year-round without letting soil stay soggy
- 2. Provide bright indirect light but avoid intense direct summer sun that can scorch skin
